Schottel has recently secured a contract to provide Rudderpropeller propulsion units for a harbour tug under construction at Tongfang Jiangxin Shipbuilding in China for the Taizhou Maritime Safety Administration.

The Maric design vessel will be equipped with two Schottel Rudderpropellers type SRP 430, featuring four-bladed CP propellers of 2.40m diameter. Each of the azimuth thrusters will be driven by a 1,920kW diesel engine at 750 rpm. This configuration will provide an expected bollard pull of 60t and a free running speed of approximately 13 knots. The new tug is set to enter operation by the end of 2020.

The 45m long and 12.6m wide tug is built primarily for vessel rescue and pollution prevention near shore as well as for towing operations. It is designed to be able to carry out oil spill recovery, firefighting and human rescue operations.

Hou Wei, Assistant General Manager, Tongfang Jiangxin Shipbuilding said: “Taizhou is an area where a lot of small fishing vessels operate, often facing typhoons. We opted for azimuth thrusters from Schottel because of their strong position in the market and traceable record of high product quality as well as service availability.”

The Schottel VarioDuct SDV45 nozzle offers high free running efficiency combined with good bollard pull performance. The company says that in conjunction with optimally designed propeller geometries, the outstanding performance characteristics of the nozzle come to the fore.
